1. An active vibration control system comprising: an electromagnetic actuator and a control element, the electromagnetic actuator being operable to apply a force on a base structure to which the active vibration control system is attachable such that vibrations of the base structure are actively controllable by the application of said force, wherein the electromagnetic actuator and the control element are relatively moveable such that the active vibration control system has at least two modes of vibration, wherein movement of the electromagnetic actuator causes movement of at least a part of the control element, wherein the electromagnetic actuator comprises a movable member, and wherein, in a first mode of vibration, the moveable member and the control element oscillate in-phase with one another, and, in a second mode of vibration, the moveable member and the control element oscillate out-of-phase with one another.
